Right now I've got a 4000 some watt earthquake amp and one 15' MTX 9500. I recently switched amps and I love this one... the sound is unbelievable. Depending on how much I get for my sub... I'll have between 500-750 dollars for new subs... I'm looking for some ear bleeding base, It's gotta be louder than the 9500! I've still got my stock head unit in my 2002 suburban. What should I spend my money on guys? I'm looking for some SQ too, but it doesn't NEED to be anything better than 9500 SQ wise, it sounds solid with rock, and thats what I'm looking for. Thanks for the help guys
